Problems solved by technology

However, for the flotation separation of high-sulfur copper ore, the actual beneficiation results cannot meet the design requirements, the separation of copper and sulfur is not ideal, the sulfur content in copper concentrate products exceeds the standard, and the recovery rate of copper concentrate is low, resulting in waste of mineral resources. , bring losses to enterprises and society

Embodiment 1

[0021] a, preparation of isobutyl allyl thiocarbamate

[0022] Add 28.7Kg of commercially available isothiocyanate into a closed stainless steel reaction kettle heated by heat conduction oil, control the temperature at 110-120°C, stir and dehydrate for 2 hours to make the water in it evaporate completely, then add 19.7g of tetrabutyl titanate, Keep the reaction temperature at 115-125°C, and start to add isobutanol dropwise. The amount of isobutanol added is 21.4Kg, and the dropwise addition is completed in 1.8-2.2 hours. Keep the temperature at 110-120°C and continue the reaction for 3 hours to complete the reaction. Stand overnight and cool down to After room temperature, fill it into a plastic-lined iron drum, and the obtained brown oily product is isobutyl allyl thiocarbamate. The effective content of isobutyl allyl thiocarbamate in this reaction can reach 75%, and the yield is about 90%. .

[0023] b, preparation of thiazonitrile ester

[0024] Add 17Kg of carbon disulfi...

Embodiment 2

[0029] Add the content of each component specified in the following Table 1 into the stirring tank, and stir and mix at room temperature for 50 minutes to obtain the collector composition of the present invention. Then the collector was used for beneficiation test of copper ore, and the test results are listed in Table 1.

Embodiment 3

[0031] Add the content of each component specified in the following Table 1 into the stirring tank, and stir and mix at room temperature for 45 minutes to obtain the collector composition of the present invention. Then the collector was used for beneficiation test of copper ore, and the test results are listed in Table 1.

Abstract

The invention relates to a high sulfur copper ore collecting agent, which is characterized by consisting of the following materials in part by weight: 40 to 50 parts of alkyl allyl thionocarbamate, 35 to 45 parts of sulfur nitrogen nitrile ester and 8 to 15 parts of alkyl xanthonic acid propionitrile ester. The collecting agent has double properties of collecting and foaming, high selectivity and high collecting capacity, can realize high-efficiency separation of copper and sulfur when the pH value is in a range from 7 to 10, can effectively improve the concentrate grade and the recovery rate, and has a wider application range.

Description

technical field [0001] The invention relates to a flotation agent for copper ore, in particular to a high-efficiency collector for high-sulfur copper ore. Background technique [0002] The demand for metals in today's world continues to grow, while mineral resources are increasingly depleted. With the continuous soaring of copper prices, all large non-ferrous metal mining enterprises and small-scale concentrators hope to find high-efficiency beneficiation agents with strong selectivity and good energy efficiency to strengthen copper without changing the original beneficiation process. The beneficiation process of mines maximizes the economic and social benefits of the enterprise. [0003] The effective separation of copper and sulfur in high-sulfur copper ore has always been a technical problem in the beneficiation industry. Most domestic copper-sulfur ore flotation collectors improve their selectivity by reducing their collection capacity, and the beneficiation of copper c...
